2.2.2 Use as Directed
The servo amplifiers are components which are built into electrical equipment or
machines, and can only be used as integral components of such equipment.
The manufacturer of the machine must generate a risk assessment for the machine, and
take appropriate measures to ensure that unforeseen movements cannot cause injury or
damage to any person or property.
If the servo amplifiers are used in residential areas, or in business or commercial
premises, then additional filter measures must be implemented by the user.
Cabinet and Wiring
The servo amplifiers may only be operated in a closed switchgear cabinet, taking into
account the ambient conditions (
➜
# 54) and the dimensions (
➜
# 196). Ventilation or
cooling may be necessary to prevent enclosure ambient from exceeding 40°C (104°F).
Use only copper wire. Wire size may be determined from EN 60204 (or table 310-16 of the
NEC 60°C or 75°C column for AWG size).
Power supply
S7xx0 : Servo amplifiers in the S7xx0 series (overvoltage category III acc. to EN 61800-
5-1) can be supplied from 3-phase grounded (earthed) industrial supply networks (TN-sys-
tem, TT-system with grounded neutral point, no more than 42kA symmetrical rated cur-
rent at 208V-10%, 230V, 240V, 400V or 480V+10%).
S7480/S7720: In case of mains voltage asymmetry >3% a mains choke must be used.
S7xx6 : Servo amplifiers in the S7xx6 series (overvoltage category III acc. to EN 61800-
5-1) can be supplied from 1-phase or 3-phase grounded (earthed) industrial supply net-
works (TN-system, TT-system with grounded neutral point, no more than 42kA sym-
metrical rated current at 110V-10% to 230V+10%).
Periodic overvoltages between outer conductor (L1, L2, L3) and housing of the servo amp-
lifier may not exceed 1000V (peak value). Transient overvoltages (< 50µs) between the
outer conductors may not exceed 1000V. Transient overvoltages (< 50µs) between outer
conductors and housing may not exceed 2000V.
Motors
The S700 family of servo amplifiers is only intended to drive specific brushless syn-
chronous servomotors, with closed-loop control of torque, speed and/or position. The
rated voltage of the motors must be at least as high as the DC bus link voltage of the
servo amplifier.
Safety
Consider the specific "use as directed" information (
➜
# 58) when you use the safety
function STO.
To achieve PL e or SIL CL3, the safe switching of the pulse inhibitor must be tested peri-
odically by analyzing the feedback signal from the safety control.
Observe the user documentation for safety cards S1-2(S3) / S2-2(S4) when you use a
safety expansion card.
